我正在尝试：

#!/usr/bin/python3
import slate

with open('/var/tmp/PhysRevB.93.014203.pdf') as fp:
    doc = slate.PDF(fp)
print(len(doc))
print(doc[0])

这给了我错误：

$python3 tstslt.py 
Traceback (most recent call last):
  File "tstslt.py", line 2, in <module>
    import slate
  File "/usr/lib/python3.5/site-packages/slate/__init__.py", line 66, in <module>
    from .classes import PDF
  File "/usr/lib/python3.5/site-packages/slate/classes.py", line 25, in <module>
    import utils
ImportError: No module named 'utils'

我可以使用PyPDF2提取文字，但要查看平板是否更好。

Answer 1

根据this issue一个slate的dependecies（pdfminer）不支持Python3

（...）

所需的“pdfminer”不起作用，因为它当前   与python 3.5不兼容。

在他们的自述文件中说明了这一点：

https://github.com/euske/pdfminer

“安装Python 2.6或更新版本。（不支持Python 3。）”

Answer 2

slate3k是python3原始slate的分支。

您可以使用pip install slate3k

安装slate3k

Answer 3

安装 slate3k 后，还必须设置模式以及如何打开文件：

#/usr/bin/python3
import slate

with open('/var/tmp/PhysRevB.93.014203.pdf', 'rb') as fp:
    doc = slate.PDF(fp)
print(len(doc))
print(doc[0])

使用python3从pdf中提取文本
